A company is in the process of deploying mobile and remote access with multiple IM&P clusters and must ensure that the user DB replicates among clusters and the Expressway-C correctly routes XMPP traffic. Which service must the engineering team turn on to accomplish this goal?
A. Cisco Discovery Protocol Agent
B. Host Resources Agent
C. MB2 Agent
D. Intercluster Sync Agent
Yes, D is correct.
If you are deploying Mobile and Remote Access with multiple IM and Presence Servers clusters, you must
configure Intercluster peer links between the clusters, and the Intercluster Sync Agent (ICSA) must be active
on all clusters. This ensures that the user database is replicated between clusters, allowing Expressway-C
to correctly route XMPP traffic.
